Answers

If triangle ABC is translated 5 units down, the coordinates of the image vertices are A′(1, −7), B′(9, −7), C′(5, −3).

The correct option among the given choices is A′(1, −7), B′(9, −7), C′(5, −3).

To determine the coordinates of the image if triangle ABC is translated 5 units down, we need to subtract 5 from the y-coordinate of each vertex of the triangle.

The given vertices of triangle ABC are A(1, -2), B(9, -2), and C(5, 2).

To translate the triangle 5 units down, we subtract 5 from the y-coordinate of each vertex.

The new coordinates of the vertices after the translation are:

A': (1, -2 - 5) = (1, -7)

B': (9, -2 - 5) = (9, -7)

C': (5, 2 - 5) = (5, -3)

Therefore, the correct option among the given choices is A′(1, −7), B′(9, −7), C′(5, −3).

In summary, if triangle ABC is translated 5 units down, the coordinates of the image vertices are A′(1, −7), B′(9, −7), C′(5, −3).

3. How does the percentage of people who would borrow from some financial institution compare to
the percentage of people who would borrow from friends or family?

Answers

The percentage of people borrowing from financial institutions generally exceeds borrowing from friends or family due to formality, legal protection, larger loan amounts, privacy, expertise, and long-term implications.

The percentage of people who would borrow from a financial institution compared to the percentage of people who would borrow from friends or family can vary depending on various factors such as cultural norms, economic conditions, individual preferences, and access to financial services. However, in general, borrowing from financial institutions is often more common and prevalent than borrowing from friends or family for several reasons.

Formality and Legal Protection: Borrowing from financial institutions offers a more formal and legally protected process. When individuals borrow from a financial institution, they enter into a contractual agreement that outlines the terms and conditions of the loan. This agreement provides a legal framework that protects both the borrower and the lender. In contrast, borrowing from friends or family often lacks the same level of formality and legal protection, which can lead to ambiguity and strain personal relationships.

Access to Larger Loan Amounts: Financial institutions typically have more capital and resources to lend larger amounts of money compared to friends or family members. If someone requires a substantial loan, such as for purchasing a home or starting a business, they are more likely to turn to a financial institution. These institutions have processes in place to evaluate creditworthiness, collateral, and other factors, allowing them to provide loans that meet the borrower's specific needs.

Privacy and Independence: Borrowing from a financial institution offers a level of privacy and independence that may be preferred by individuals. Some people might feel uncomfortable disclosing personal financial details or discussing their financial challenges with friends or family. Financial institutions provide a professional environment where individuals can maintain privacy and retain control over their financial matters.

Expertise and Financial Advice: Financial institutions employ professionals with expertise in lending and financial management. When borrowing from a financial institution, borrowers can benefit from the advice and guidance of these professionals. They can help borrowers understand the terms of the loan, explore different options, and make informed financial decisions. Friends and family members may not possess the same level of financial knowledge or experience, limiting their ability to provide comprehensive advice.

Long-Term Implications: Borrowing from friends or family can have long-term implications for personal relationships. Financial transactions have the potential to create tension, conflicts, or misunderstandings among individuals, especially if there are difficulties in repaying the borrowed amount. Relying on financial institutions can help maintain healthy personal relationships, as the borrowing and lending processes are conducted on a professional level, minimizing the emotional and relational strain that can arise from borrowing from loved ones.

⇒ AB = √ (-4 + 3)² + (9 - 7)²

⇒ AB = √1 + 4

⇒ AB = √5

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

⇒ A'B' = √ (3 - 3)² + (6 + 4)²

⇒ A'B' = 10

8. For positive real numbers a, b, and c, the expressions albici and Vabac are equivalent. What are the values
of p, q, and r?

Answers

Answer:

Step-by-step explanation:

To find the values of p, q, and r in the expression albici = Vabac, we need to equate the corresponding parts on both sides.

From the given equation, we have:

p * (a * b) * (c * i) = q * (a * b * a * c)

Comparing the exponents of a, b, and c on both sides, we get:

p = q * a^2

1 = q * c

To determine the value of r, we can use the fact that albici and Vabac are equivalent. The radical symbol (√) represents taking the square root.

√(a * b * c * i) = √(a * b * a * c)

This implies that:

√(a * b * c * i) = √(a^2 * b * c)

Comparing the exponents of a, b, and c on both sides, we get:

1/2 = 2 * p * q * r

Combining all the equations, we have:

p = q * a^2

1 = q * c

1/2 = 2 * p * q * r

To find the specific values of p, q, and r, we need additional information or equations involving a, b, and c. Without more context or equations, it is not possible to determine the exact values of p, q, and r.

From equation (2), we can express x in terms of z:
2x = -9z - 5
x = (-9z - 5) / 2 ...(4)

Substitute equation (4) into equations (1) and (3):

From equation (1):
4((-9z - 5) / 2) - y + 3z = 12
-18z - 10 - y + 3z = 12
-15z - y = 22 ...(5)

From equation (3):
((-9z - 5) / 2) + 4y + 6z = -32
-9z - 5 + 8y + 12z = -64
3z + 8y = -59 ...(6)

Now we have a system of two equations in terms of y and z.

To solve the system, let's multiply equation (5) by 3 and equation (6) by 15 to eliminate z:

-45z - 3y = 66 ...(7)
45z + 120y = -885 ...(8)

Add equations (7) and (8):
-3y + 120y = 66 - 885
117y = -819
y = -7

Substitute y = -7 into equation (7):
-45z - 3(-7) = 66
-45z + 21 = 66
-45z = 45
z = -1

Substitute y = -7 and z = -1 into equation (4):

You have not provided enough information to determine your total water bill.

You have only given the amounts of your individual bills from Metro Water Services and Madison Suburban Utility District.

To find your total water bill, you simply need to add the two bills together.

So, the total amount you owe for water this month would be:

Total water bill = [tex]$36.34 + $26.03[/tex]

= [tex]$62.37[/tex]

It appears that you may have forgotten to include the full amount of your water bill by accident.

Simple addition of the separate bill amounts yields the following sum:

Kenya wants to open a savings account at a bank. The bank offers a savings account that pays
out 8% annual interest. If Kenya wants at least $7,000 in his account after 15 years, how much does
Kenya need to put in the account initially?

Answers

Kenya needs to initially put in the amount of $2,208.2in the account to have at least $7,000 after 15 years.

We can use the formula for compound interest:

A = P(1 + r/n)ⁿ

where A is the amount of money in the account after t years, P is the initial principal, r is the annual interest rate (as a decimal), and n is the number of times per year the interest is compounded.

Here, we want to find P, so we can rearrange the formula as:

P = A / (1 + r/n)ⁿ

We are given that r = 0.08 (8% interest) and n = 1 (interest is compounded annually).

We also know that A = $7,000 and t = 15 years.

So we can plug in these values and solve for P:

P = 7000 / (1 + 0.08/1)¹⁵

P = 7000 / (1.08)¹⁵

P ≈ $2,208.2

Therefore, Kenya needs to initially put in approximately $2,208.2in the account to have at least $7,000 after 15 years.

Assuming a normal distribution of operating expenses, estimate the percentage of regional phone companies whose operating expenses were closer to the mean than the operating expenses of Company A were to the mean. (Round your answer to two decimal places.)

Answers

The probability of the values of X that are less than 21 is 0.97725.

We have,

The term "standard deviation"  refers to a measurement of the data's dispersion from the mean.

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

u = 20

and SD = 2.25

To find P(X < 21)

So, P(X < 21 )

= 1 - P(X > 21)

Now, P(X > 21)

= P(Z >  [(21–20)/2.25]

= P( Z > 1/2.25)

= P(Z > 0.444)

= 0.02275

So, the required probability = P(Z < 21) = 1 - 0.02275= 0.97725

Find the simple interest owed if $340 is borrowed at 6.6% for 9 years

Answers

The simple interest owed on a $340 loan at 6.6% interest for 9 years is $201.96.

How to find simple interest?

The simple interest formula is expressed as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time.

Given that:

Principal P = $340

Interest Rate r = 6.6%

Time t = 9 years

First convert the interest rate from percent to decimal:

Rate = r/100

Rate = 6.6/100

Rate = 0.066

Now, plug the values into the above formula and solve for interest.

I = P × r × t

I = $340 × 0.066 × 9

I = $201.96

Therefore, the simple interest is $201.96.

A track coach recorded the time it took for each of her athletes to run a mile. She plans to display the results with a histogram. Which of the following will it show? Select all that apply. (please help as soon as possible. thanks :))

Answers

The histogram will show the distribution of the athletes' mile running times. It will provide a visual representation of the frequency or count of athletes falling within different time intervals.

1. Determine the time intervals or "bins" for the histogram. For example, you might have bins of 5-second intervals, such as 0-5 seconds, 5-10 seconds, and so on.

2. Count the number of athletes who fall within each bin. For instance, if three athletes completed the mile in the 0-5 second bin, and five athletes completed it in the 5-10 second bin, record those counts.

3. Plot the bins on the x-axis of the histogram and the corresponding frequency or count on the y-axis.

4. Draw rectangles (or bars) on the histogram, with the height of each bar representing the frequency or count of athletes within each bin.

5. Label the axes and add a title to the histogram for clarity.

The resulting histogram will provide a visual representation of how the athletes' mile running times are distributed, allowing you to observe any patterns or trends.

How to estimate a non-exact square root?

The estimate of a non-exact square root of x is done finding two numbers, as follows:

The greatest number less than x that is a perfect square, which we call a.The smallest number greater than x that is a perfect square, which we call b.

For this problem, we want to estimate the root to the hundredth's place, hence the number that we must compare is:

44 x 10^4 = 440000.

(as each 10² is equivalent to the square root of a decimal digit).

Then the numbers are:

663² = 439569 < 440000.664² = 440896 > 440000.

Hence the square root is approximated as follows:

663/100 = 6.63.

The numbers arranged in the correct order are:

-3 = -3

-3 < | -1 |

0 < | 1 |

2 > | 0 |

3 > | 1 |

We have,

-3 = -3:

This is a true statement because -3 is indeed equal to -3.

-3 < | -1 |:

This is also a true statement.

The absolute value of -1 is 1, so we are comparing -3 and 1.

Since -3 is less than 1, the inequality is true.

0 < | 1 |:

Again, this is a true statement.

The absolute value of 1 is 1, so we are comparing 0 and 1.

Since 0 is less than 1, the inequality holds true.

2 > | 0 |:

This is also a true statement.

The absolute value of 0 is 0, so we are comparing 2 and 0.

Since 2 is greater than 0, the inequality is true.

3 > | 1 |:

Once again, this is a true statement.

The absolute value of 1 is 1, so we are comparing 3 and 1.

Since 3 is greater than 1, the inequality holds true.

Therefore,

By arranging the given numbers in this order: -3, -3, -1, 0, 1, 2, 3, all of the number sentences become true.

At Chairs and More, assemblers are paid according to the following differential piece rate scale: 1−25 chairs in a week, $10 each; 26−40 chairs, $13 each; and $17.50 each for every chair over 40. Salina Grant assembled 47 chairs in one week. Find her gross pay.

Answers

Answer:

To find Salina Grant's gross pay, we need to calculate the pay for each range and add them together.

For the first 25 chairs, Salina will be paid $10 for each chair, so her pay for this range is:

25 chairs x $10 per chair = $250

For the next 15 chairs (26-40), Salina will be paid $13 for each chair, so her pay for this range is:

15 chairs x $13 per chair = $195

For the remaining 7 chairs (over 40), Salina will be paid $17.50 for each chair, so her pay for this range is:

7 chairs x $17.50 per chair = $122.50

Adding up all three ranges, Salina's gross pay is:

$250 + $195 + $122.50 = $567.50

Therefore, Salina Grant's gross pay for assembling 47 chairs in one week is $567.50.

Then, answer the question.Voluntourism: An Opportunity Too Good to be TrueA Speech to the Student Body of Evergreen High[1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use.
